NAME

device_unregister - unregister device from system.

SYNOPSIS

void device_unregister (struct device * dev);

ARGUMENTS

dev device going away.

DESCRIPTION

We do this in two parts, like we do device_register. First, we remove
it from all the subsystems with device_del, then we decrement the
reference count via put_device. If that is the final reference count,
the device will be cleaned up via device_release above. Otherwise, the
structure will stick around until the final reference to the device is
dropped.
